With an enormous growth of digital data in the cloud storage, effective methods need to be employed to reduce hardware costs, meet the bandwidth requirements and to increase storage efficiency. It can be established by using Data Deduplication. Data Deduplication is a technique of detecting and eliminating the redundant copy of data.  Thus by storing less data, it would need less hardware and would be able to better utilize the existing storage space. Data deduplication plays an important role in data transmission in various data intensive network and cloud applications.  Deduplication system can use either fixed or variable size algorithms that mainly focuses on the requirement of storage space reduction by storing only single copy of data. This paper review the various chunking techniques that partition data stream or file into chunks of variable size.

Abstract


With an enormous growth of digital data in the cloud storage, effective methods need to be employed to reduce hardware costs, meet the bandwidth requirements and to increase storage efficiency.

Data Deduplication is a technique of detecting and eliminating the redundant copy of data.  Thus by storing less data, it would need less hardware and would be able to better utilize the existing storage space. Data deduplication plays an important role in data transmission in various data intensive network and cloud applications.  Deduplication system can use either fixed or variable size algorithms that mainly focuses on the requirement of storage space reduction by storing only single copy of data. This paper review the various chunking techniques that partition data stream or file into chunks of variable size.
